LABORATORY IN BRIEF
The Laboratory of Self-Organization System Modeling (LSSM) is a basic
laboratory of the IEC in the field of investigation of complex dynamic
system.
The main aims and tasks of the LSSM are the following:
-
· development and investigation of complex dynamic system models received
on the basis of experimental data by input-output representation and state
space methods;
-
· creation of effective computer technology for digital signal processing
of different physical nature.
The LSSM was established at the IEC in 1993. But the researches in domain
of dynamic system modeling have been carried out by the main groups scientists
from this laboratory since middle 80th.
STAFF
Prof., D.Sc. Alexander M.Krot has been elected as the head of the lssm
in 1993. Now the lssm has 10 persons, including 3 senior scientists with
Ph.D. degree A.Boriskevich, H.Minervina, M.Dolgikh.
The middle age of the LSSM collaborators is 31 (the head of the lssm
is 35 years old).
RESEARCH FIELDS
Principal scientific areas of interest of the lssm are as follows:
-
· nonlinear dynamic system identification and modeling;
-
· fast algorithms and procedures;
-
· spectral analysis in discrete function bases;
-
· digital filtering and restoration;
-
· compression of information;
-
· spectral-correlation identification of signals (images);
-
· complex system state recognition;
-
· optimal discrete control of dynamic objects.
Applications where these tasks have been and are used:
-
· digital signal and image processing (mainly
medical nature);
-
· diagnostics and prediction of dynamic system behavior.
The following applications were created:
-
· software of 1D and 2D digital spectral analysis with 2-3 times lower
computational complexity, more than 2 times lower computational error,
with 1,5-2 times higher resolution of analysis as compared to known approaches;
-
· the digital 1D and 2D FIR-filters (direct and inverse) were synthesized
on the basis of fast Fourier-like transform algorithms and sectionalization
convolution methods;
-
· software for accelerated compressing of signals and images based on new
fast algorithms of 1D and 2D discrete orthogonal transforms, which allows
to reduce information up to 4-8 times and increase the compressing speed
in 2-3 times;
-
· software for restoration of signal and images, distorted by means of
blur and defocusing;
-
· software for correlative-extremal identification of digital images reduced
the object detection time in 1,5-2 times;
-
· a new approach to design of dynamic object control algorithms based on
polynomial Diophantine equations.
Systems and software created in the lssm have been inculcated and used
at the Institute of Precise Instrument Building (Moscow, Russia), the Industrial
Amalgamation "AvtoVAZ" (Toliatti, Russia), the Industrial Amalgamation
"Integral" (Minsk, Belarus), the Science Amalgamation "Algorithm" (Tashkent,
Uzbekistan), the Institute of Applied Astronomy (St.-Petersburg, Russia),
the Institute of Nuclear Physics of the Russian Academy of Sciences (St.-Petersburg,
Russia), the Academic Science Complex "Institute of heat and mass exchange"
(Minsk, Belarus), the Department of General Physics of the Belarusian State
University (Minsk, Belarus), the State Institute of Applied Optics (Kazan,
Russia), the Science-Industrial Amalgamation "Geophysics" (Moscow, Russia),.

TRAINING
The lssm scientists participate in a teaching process at the following
levels:
-
· graduate level. The LSSM has a strong links with Department of Radiophysics
of the Belarusian State University (BSU) and Department of Radioengineering
Systems of the Belarusian State University of Informatics and Radioelectronics
(BSUIR). D.Sc. A.M.Krot works part-time as Professor at the Department
of Radioengineering Systems of the BSUIR. He delivers the lectural course
"Digital signal processing" and seminars;
-
· postgraduate level. In 1991 A.M. Krot received D.Sc. degree. Three Candidates
of sciences (Ph.D.) have been prepared under his scientific leadership:
H.B.Minervina (1989), B.H.Abdurakhmanov (1992), M.N.Dolgikh (1993). Now
the LSSM has five postgraduate students.
